Description

The invention relates to a method and a device for processing a flowable food mass.

A method and a corresponding device for shaping and cooling a flowable food mass, in particular hot melted cheese, is known from DE 103 28 905, for example. Therein, the food mass is shaped into a product band by means of two cooling belts guided by shaping rollers and is cooled during further transport. Shaping the hot product into a wide band having an adjustable and homogeneous thickness is a technical challenge in particular, since the melted cheese must first have a temperature of over 80° C. in order to be formable. Within the scope of further processing, cooling must be carried out rapidly and, primarily, homogeneously, without the product band becoming deformed. After cooling, the product band is initially cut into strips, which are placed on top of one another, and are cut, via transverse cutting, into stacks of cheese slices lying on top of one another. The finished stacks are packaged “slice-on-slice”.

This type of production makes it possible to produce cheese slices in mass quantities and to package these cheese slices in relatively large bundles. This type of packaging is only suitable, however, for types of cheese in which the consistency of the slices is such that they have a certain tearing resistance and can be easily lifted off of one another even in the stacked state. Types of cheese having a particularly creamy and soft consistency are suitable for production in this manner only in certain ways and, primarily, being stacked on top of one another in slices without placement of a separating sheet therebetween.

The use of a separating film in such a method is described in the subsequently published document DE 10 2011 103 826. Therein, a method for shaping and cooling initially hot and therefore flowable melted cheese is described, which is applied onto a moving metallic cooling belt via a supply nozzle. In this case, a shaping roller acting upon the cooling belt is used to shape individual shaped bodies, in particular finished shaped slices, from the melted cheese, to release these shaped bodies from the molding cavities of the shaping roller and leave these on the moving cooling belt to cool. A carrier film that holds the shaped bodies together is required in order to process these individual shaped bodies. At the end of the cooling process, the film is cut and can be used as intermediate film during stacking. In this method, the separating sheets are therefore already provided during the shaping of the food mass and are cut, along with the product lying thereon, into corresponding slices. A separating film between the cheese band and a conveyor belt is also disclosed in U.S. Pat. No. 4,7435,817.

It has proven to be difficult, however, to cut a cheese band, which is lying on a film, together with the film into exact strips without the product being changed thereby.

The problem addressed by the invention is therefore that of improving the known method for processing flowable food masses such that a particularly soft and creamy food product can also be brought into slice form, in mass quantities, and stacked to form stacks of slices.

The problem addressed by the invention is solved by the method according to claim 1 and the device according to claim 9. Particular embodiments are mentioned in the dependent claims.

The gist of the invention is the use of a carrier film arrangement having a plurality of carrier film webs, which are disposed next to one another without separation (“without gaps”) in the transport direction and, in particular, which partially overlap one another. This carrier film arrangement forms a sealing support onto which the flowable product is applied, shaped to form a product band, and cooled. At the end of cooling, it is merely necessary to cut the product band lengthwise into product strips without the film underlayer and separate the product strips from one another by means of the individual carrier film webs.

The invention therefore relates to a method for processing a flowable food mass, wherein the food mass is introduced, via a supply nozzle, into a gap between two moving, vertically disposed cooling belts, which are metallic, in particular, and are shaped into a food band or product band having a defined thickness. The carrier film arrangement is provided between the first cooling belt and the product band, wherein the product band is moved together with the carrier film arrangement in a transport direction. The method is characterized, in particular, in that the carrier film arrangement comprises a plurality of carrier film webs, which are disposed next to one another without gaps in the transport direction and, in particular, partially overlap one another, wherein the product band extends seamlessly over the plurality of carrier film webs, which are disposed next to one another. The product band is cut on the carrier film webs into product strips extending parallel to the transport direction by cutting means, in particular by cutting rollers.

The product band is cut, exclusively, into strips by means of the cutting means of the longitudinal cutting device, while the carrier film webs remain intact. The defined thickness of the food band can be specified and adjusted in a defined manner by the distance between two shaping and redirection rollers in the region of the filling nozzle, wherein one of the cooling belts is guided by the rollers in each case.

In this manner a relatively wide product band can be prepared on a carrier film arrangement and initially cooled by means of the cooling belts. The initially wide product band can then be cut, in a very simple manner, into strips having virtually any strip width and fed to further processing. The advantage is that the product strips that are produced continue to remain on the carrier film web associated with the strip. The carrier film web can therefore be used not only as a “vehicle” for the uncut product band in the region of the cooling belts, but is also a carrier for the product for subsequent processing steps as well. This method permits products to be processed virtually independently of the consistency thereof. Particularly creamy and soft melted cheese can be processed, in particular.

Given that the carrier film arrangement already comprises a plurality of individual carrier film webs, which are disposed next to one another without gaps, the longitudinal cutting of the films together with the food band is omitted. Such a cutting step can therefore be omitted, thereby significantly simplifying the processing method. The cut food strips can then be separated from one another simply by moving the individual carrier strip bands apart from one another. The cutting means for the longitudinal cutting can be very easily dimensioned, since these only need to cut through the mostly soft food band, but not the carrier film webs, which are relatively viscous and robust, because these are tension-resistant. In summary, the method according to the invention makes it possible to use the carrier film for shaping and cooling as a separating sheet as well, wherein, unlike the food mass, the carrier film need not be subjected to longitudinal cutting.

The expression “disposed next to one another without gaps” is intended to mean an arrangement of the carrier film webs in which food mass is prevented from passing between the carrier film webs, which are disposed next to one another, even if a very small gap were present, as considered exactly. A carrier roll web can have a width of approximately 50 to 150, in particular approximately 100 mm, for example, wherein the widths of corresponding processed cheese slices have a similar dimension.

The product strips are preferably ultimately separated from one another by the carrier film webs moving apart from one another and can be fed to further processing. In particular, the product strips can be cut into individual slices by transverse cutting and these product strips can be stacked on top of one another in stacks.

It is very particularly preferred, however, for adjacent carrier film webs to overlap transversely to the transport direction. It can thereby be ensured that an underlying region of a carrier film web is not wetted with the food product. After separation, a corresponding overhang of carrier film web remains, which is free of food mass. In particular when the carrier film web is subsequently also used as a separating sheet in the stacking of a plurality of food slices, a type of food-free grip remains, with the aid of which the individual slices can be grasped. An underlying region of a carrier film web refers to a region of a carrier film web that does not come into contact with the food band, since the overlapping part of the adjacent carrier film web is disposed between this region and the food band. In contrast thereto, an overlying region refers to a section of a carrier film web that can come into contact with the food band, since this region is not covered by the overlapping section of the adjacent carrier film web. Instead, the overlying region can, in turn, cover an underlying region of the adjacent carrier film web. The overhang can be, preferably, at least 4 mm or maximum 20 mm, wherein the overhang can be based entirely on the dimensions of the grip for the separating sheet.

Preferably, the cutting paths between two adjacent food strips, which are created in the food band by the cutting means, are aligned flush with a respective overlying longitudinal edge of a carrier film web. In contrast thereto, an underlying longitudinal edge of a carrier film web does not need to be aligned with a cutting edge. By aligning the overlying longitudinal edge with the cutting edge, a flush termination between the food strip and the carrier film web is obtained without longitudinally cutting both the food band and the carrier film web.

Preferably, parts of the carrier film web remain, as a separating sheet, in contact with the food product that is produced, in particular a cheese slice, and are packaged together with the slice. Further cutting operations, in particular transverse cutting, can follow the method according to the invention.

Preferably, at least one auxiliary film is disposed, at least in sections, between a first cooling belt and the food belt, wherein the auxiliary film moves together with the food band in the transport direction. The auxiliary film is intended, in particular, to prevent the food band from adhering to the second cooling belt. Different films having different adhesion values are used in order to ensure, in particular, good removal of the preferably very soft or creamy food product from the auxiliary film. The films are selected, in particular, such that a first adhesion value between the carrier film web and the food band is greater than a second adhesion value between the auxiliary film and the food band. The adhesion values can be set by means of the material selection or the selection of the surface texture of the films.

The auxiliary film preferably wraps around the second cooling belt, wherein the second auxiliary film is fixedly connected to the second cooling belt at a transverse edge located upstream in the transport direction, for example being bonded thereto. The length of the auxiliary film is greater than the circumference of the second cooling belt. In order to apply the auxiliary film, this auxiliary film is initially fixed on the second cooling belt via the transverse edge located at the front, preferably being bonded thereto. The second cooling belt is then moved in the transport direction, whereby the auxiliary film wraps around the second cooling belt until this cooling belt is finally wrapped around completely. Since the auxiliary film is longer than the circumference of the second cooling belt, the second cooling belt is wrapped around at least once without a gap. A very simple method for applying and replacing such an auxiliary film on a cooling belt is hereby provided. The auxiliary film can therefore be pulled behind the cooling belt like a train and will thereby orient itself on the cooling belt. A type of floating support on the cooling belt results, in particular, when adhesion between the cooling belt and the auxiliary film is very slight. Folds can be prevented from forming in the auxiliary film or can at least straighten themselves out. The auxiliary film can remain on the second cooling belt for a certain period of time, in particular a few days, and can then be replaced by a new auxiliary film.

It is furthermore preferable for a separating means, in particular soybean oil or lecithin oil, for example, to be applied between the food band and the auxiliary film. The auxiliary film preferably has a width, which is at least as wide, in particular wider, than the sum of the carrier films, possibly minus the overhangs, and can have a width that is 3- to 5-fold the width of the carrier film, for example, possibly minus the sum of the overhangs, i.e. approximately 450 mm, for example. The auxiliary film is preferably provided with a layer on the side facing the food band that repels food, in particular cheese. The carrier film webs preferably do not have such a layer. The auxiliary film is preferably separated from the food band before the food band is cut into food strips. The cutting is then preferably carried out without the auxiliary film. The use of the auxilary film is not necessarily coupled to the embodiment of the above-described carrier film arrangement comprising a plurality of carrier film webs disposed next to one another. Instead, this use combined with the features of the preamble of claim 1 can also be a separate invention.

The adhesion between the carrier film web and the cooling belt can be increased by means of corona treatment on the surface of the carrier film web that is in contact with the cooling belt. Polypropylene, for example, is suitable as the material for the carrier film webs and for the auxiliary film.

In order to improve the alignment of the auxiliary film on the second metallic cooling belt, a separating means, in particular a separating oil, is preferably introduced between the second cooling belt and the auxiliary film. This enables the auxiliary film to become better aligned, automatically, on the second cooling belt. As a result, the homogeneity of the surface of the food product covered by the auxiliary film can be improved, since tensions between the auxiliary film and the food band are better compensated by means of the floatability of the auxiliary film on the second cooling belt. Folds are prevented from forming in the second auxiliary film. This applies in particular for auxiliary films that wrap around the second cooling belt in an annular manner.

The invention further relates to a device for processing a flowable food mass, in particular a spreadable cheese or processed cheese, which can implement a method according to the aforementioned claims. In such a device, in particular, the food product is processed to form a food band having a defined thickness. The device comprises the following units. At least two vertically disposed cooling belts, which are metallic, in particular, a supply nozzle for introducing the food product in a flowable state into a gap, which is formed between the two cooling belts. A carrier film arrangement is provided between the first cooling belt and the food band, wherein the food band can be moved together with the carrier film arrangement in a transport direction. Furthermore, cutting means are provided for cutting the food band on the carrier film arrangement into food strips extending parallel to the transport direction.

According to the invention, the carrier film arrangement comprises a plurality of carrier film webs, which are disposed next to one another and, in particular, partially overlap one another. The cutting means are oriented such that cut edges between two adjacent product strips, which are produced by the cutting means, are aligned with longitudinal edges of the overlying carrier film webs. Reference is made to the advantages mentioned above with respect to the method, and to further potential embodiments.

The device preferably comprises guide means, in particular redirection rollers, by means of which the carrier film webs, which are disposed next to one another, can be separated from one another. The guide means are disposed downstream of the cutting means in the transport direction. In other words, the food band is first cut into food strips, and then the carrier film web is separated from one another by the guide means.

Types of cheese that are very creamy and/or sticky are those, in particular, that have one or more of the following parameters:

The hardness (the maximum force during the first deformation) is less than 500 g, in particular less than 300 g, in particular approximately 244 g. For comparison: conventional types of processed cheese can have a hardness of approximately 1146 g.

The adhesiveness (the work required to overcome adhesion forces between the processed cheese and the contact surface) is less than −180 g*sec, in particular less than −180 g*sec, in particular approximately −184 g*sec. For comparison: conventional types of processed cheese can have an adhesiveness of approximately −154 g*sec.

The springiness (the extent to which a deformed cheese sample returns to the original state before the deformation) is approximately 0.92, which approximately corresponds to the springiness of conventional types of processed cheese.

The cohesiveness (minimal force during the first deformation of a cheese sample) is approximately 0.74, which approximately corresponds to the springiness of conventional types of processed cheese.

The gumminess (energy required to dissolve a cheese sample and bring this into a swallowable state) is less than 400 g, in particular less than 200 g, in particular approximately 181 g. For comparison: conventional types of processed cheese can have a gumminess of approximately 842 g.

The chewiness (energy required to chew a cheese sample) is less than 400 g, in particular less than 200 g, in particular approximately 167 g. For comparison: conventional types of processed cheese can have a gumminess of approximately 784 g.

    • a) in a side view,
    • b) in a front view.

FIG. 1 shows the unwinding of a carrier film arrangement 21 during the method according to the invention. In the present example, the carrier film arrangement 21 comprises three carrier film webs 231, 232, 233, which are disposed next to one another without gaps. Two carrier film webs 23 disposed next to one another overlap in each case by an overhang 17 and lie on top of one another in the region of the overhang 17. An overlying longitudinal edge 25 of the second carrier film web 232 overlaps the first carrier film web 231 and subsequently comes into contact with the food band. An underlying longitudinal edge of the second carrier film web 232, which faces the third carrier film web 233, is covered by the third carrier film web 233 and therefore does not come into contact with the food band 10. The carrier film webs 23 are shown only in sections. In an upper region, which is not shown, film rollers 16 of a film roller arrangement 15 adjoin one another, from each of which one of the carrier film webs 23 is unwound in order to implement the method. The carrier film webs 23 are then unwound in the transport direction T and reach a redirection region C (FIG. 2), in which redirection rollers or the like are provided and with the aid of which the carrier film webs 23 can be separated from one another. As an alternative, the carrier film webs disposed next to one another can also be fed to a common transverse cutting device. The individual carrier film webs 23 are placed on a non-illustrated, first cooling belt, as explained in greater detail further below.

FIG. 2 shows the carrier film arrangement 21 from FIG. 1, wherein food mass in the form of processed cheese is now placed on the carrier film arrangement 21. Initially, in section A, the processed cheese forms a processed cheese band 10, which is applied in liquid form or at least semifluid form onto the carrier film web 23. The processed cheese band 10 extends seamlessly over the three carrier film webs 23 and is moved together with the carrier film webs 23 in the transport direction T.

Cutting rollers 6 (FIG. 6) take effect in region B and cut the processed cheese band 10 into individual processed cheese strips 131, 132, 133. The cutting rollers 6 create cutting paths 14, which are exactly aligned with the overlying longitudinal edges 25 of the carrier film webs 23. It is possible to provide automatic film edge detection, in particular with an optical sensor, which detects the position of the overlying longitudinal edges 25 of the film web. The cutting means 6 only cut the processed cheese band 10, however, and not the carrier film webs 23. Redirection rollers 22 (FIG. 6) are provided in region C, by means of which the carrier film webs 23 are separated from one another. In the present case, the first and the third carrier film webs 231 and 233 are moved outwardly, while the second carrier film web 232 is further conveyed, in a straight line, in the center. The separation can take place in other directions as well. Furthermore, the separation of adjacent bands can take place after a transverse cutting procedure. It is evident that the carrier film webs 23 are still in contact with the processed cheese strips 13 lying on top thereof. It is further evident that the overhang 17 produced by the overlapping arrangement of the carrier film webs 23 is now exposed after the separation and forms a section that is free of processed cheese and is suitable for use as a grip. Transverse cutting of the processed cheese strips 13 into processed cheese slices 4 is implemented in region D. The processed cheese slices 4 can then be stacked on top of one another, as shown in FIG. 3. The parts of the carrier film web 23 remain, as a separating sheet 8, between the processed cheese slices 4 stacked on top of one another. It is evident that the overhang 17 projects slightly beyond the stack 7 of processed cheese slices 4 and thereby provides a way to grip individual slices. The size of the grip on the separating sheets 8 can be defined via the selection of the size of the overhang 17.

FIGS. 4 to 6 will be described jointly in the following. These figures show the device for implementing the claimed method, on which the carrier film arrangement 21 according to FIGS. 1 and 2 is used. A few of the components of the device are not shown in FIG. 6, and therefore the course of the processed cheese band 10 is largely shown. The device comprises a first metallic cooling belt 11, a second metallic cooling belt 12, and a third metallic cooling belt 18, and therebetween the processed cheese band 10 from a supply nozzle 2 to the cutting rollers 6. In the region of the supply nozzle 2, hot melted cheese 1 is introduced into a gap 3 provided between the first metallic cooling belt 11 and the second metallic cooling belt 12. The thickness of the processed cheese band 10 that is produced is adjusted by means of the distance between the cooling belts. The distance between the cooling belts can be specified in a defined manner by non-illustrated redirection rollers at the upper and lower regions of the cooling belts. The first metallic cooling belt 11 is partially covered by a carrier film arrangement 21, which is largely disposed in entirety between the processed cheese band 10 and the first metallic cooling belt 11. A plurality of film rollers 16 disposed upstream of the supply nozzle provides the individual carrier film webs 23, which form the carrier film arrangement 21. As viewed in the transport direction T, the film rollers 16 are disposed one behind the other with roller axes extending transversely to the transport direction T, but these film rollers overlap transversely to the transport direction T, and therefore the unwound carrier film webs 23 also overlap, as previously shown in FIGS. 1 and 2.

The carrier film webs 23 are now moved together with the metallic cooling belts 11, 12, in the transport direction T, carrying along viscous melted cheese 1, which is then processed to form the processed cheese band 10. The carrier film webs 23 remain in constant contact with the processed cheese band 10 and, together with the processed cheese band 10, thereby wrap around the second metallic cooling belt 12 and the third metallic cooling belt 18. In order to ensure that the processed cheese band 10 can become subsequently detached from the second metallic cooling belt 12, an auxiliary film 24 is disposed between the second metallic cooling belt 12 and the processed cheese band 10. The auxiliary film 24 has a relatively low adhesion value compared to the processed cheese band 10 and is therefore easy to remove from the processed cheese band 10. The carrier film webs 23 have a higher adhesion value than the auxiliary film 24 as compared to the processed cheese band 10, and therefore the processed cheese band 10 adheres better to the carrier film web 23 than to the auxiliary film 24. The auxiliary film 24 therefore detaches from the processed cheese band 10 in the upper redirection region of the third metallic cooling belt 18, while the processed cheese band 10 remains on the carrier film webs 23 and is conveyed in the direction of the cutting rollers 6. The auxiliary film 24 annularly encloses the second metallic cooling belt 12, and therefore the auxiliary film 24, together with the second metallic cooling belt 12, executes a common rotational movement. In contrast thereto, the carrier film webs 23 are designed as a type of endless film, which are unwound from a relatively large film roller and then, as the separating sheet, exit the arrangement together with the processed cheese.

The cutting rollers 6 cut cutting paths 11 into the processed cheese band 10, thereby producing individual processed cheese strips 13, as previously explained by reference to FIG. 2. In the present case, a total of five processed cheese strips are created, which are disposed parallel to one another and lie on five corresponding carrier film webs 23, which are disposed next to one another. The absolute number of processed cheese strips can vary, wherein it must be ensured, however, that the number of processed cheese strips that is cut is never fewer than the number of carrier film webs that are present. Exactly one carrier film web must be assigned to each processed cheese strip.

The redirection rollers 22 are disposed downstream of the cutting rollers 6. By means of the redirection rollers 22, the processed cheese strips 13 can be fed into different directions, thereby separating the processed cheese strips 13. The processed cheese strips 13 still lie on the carrier film webs 23 at this point.

A stripper 9 is provided in the upper redirection region of the second metallic cooling belt 12, which ensures that the auxiliary film 23 is always flat upon arrival into the region of the supply nozzle 2.

In order to reduce the adhesion between the auxiliary film and the processed cheese band 10, a separating means 5, in particular a separating oil, is applied onto the auxiliary film 24, namely onto the side that comes into contact with the processed cheese band 10. The stripper 9 can further serve to remove excess separating oil or to evenly distribute the separating oil 5 on the auxiliary film 24. Furthermore, a separating means is applied onto the other side of the auxiliary film 24, namely the side that comes into contact with the second metallic cooling belt 12, wherein this separating means ensures automatic alignment of the auxiliary film 23 on the metallic cooling belt 12. It is therefore possible to prevent folds from forming in the auxiliary film 24.

FIG. 7 illustrates the arrangement of the auxiliary film web 24 on the second metallic cooling belt 12. The auxiliary film web 24 is wound onto the second metallic cooling belt 12. A transverse edge 27 of the auxiliary film web 24 disposed at the front in the transport direction is fastened to the second metallic cooling belt by means of bonding 19. The bonding can be in the form of an adhesive strip. If the second metallic cooling belt 12 now moves in the transport direction, it pulls the auxiliary film web 24 behind itself in the manner of a train. Fixation of the transverse edge 28 located downstream of the transport direction T is therefore not required. The auxiliary film web 24 has a length in the longitudinal direction that is greater than the circumference of the second metallic cooling belt 12. An overhang 20 overlaps the bonding 19 and the transverse edge 27 of the auxiliary film web 24 located in the front in the transport direction T. The entire second metallic cooling belt 12 is therefore wrapped around at least once, without gaps, by the auxiliary film web 24.

The statements made with respect to the exemplary embodiment can also apply for other types of food, to the extent this is possible, and are not limited to processed cheese. Furthermore, the cooling belts do not necessarily need to be metallic.
